Get a grip man! It's CHEESE!
On a train you actually get to see the countryside. Sometimes you can see things from a plane but its different from 30,000 ft and if its cloudy you cant see anything. Its also probably better for meeting people since most people that are flying are too busy and irritated to be fun to talk with.
If trains were more punctual and had better routes I would probably use them a lot depending on how much time I have to get to where Im going. You waste a lot of time flying by having to get to the airport hours before your flight leaves and waiting to get your bags when you get off. On a train you can arrive at the station a few minutes before it leaves and walk right on. When you get to your destination you can walk right off with your bags.
